View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Copper Alloy No. 845 was formerly identified as 78-3-7-12 alloy or 78 Semi-Red Brass. It is a free-cutting copper-tin-lead-zinc alloy and is characterized by good casting properties, moderate strength and ductility, excellent machinability and good corrosion resistance. Among its many uses are low-pressure valve fittings, plumbing fixtures and general hardware fittings.
